Abstract:
A liquid crystal medium, which has a liquid crystal phase over a wide temperature range, a large refractive index anisotropy, and a large dielectric anisotropy, and exhibits an optically isotropic liquid crystal phase, is provided. The liquid crystal medium is characterized by containing a liquid crystal compound having four benzene rings and a difluoromethyleneoxy group, and a chiral reagent, and exhibiting an optically isotropic liquid crystal phase.
